International Society of Radiographers and Radiological Technologists (ISRRT) is a non-governmental organization [1] formed in 1959 [2] which aims to give direction to the Radiological profession as a whole through collaboration with national representative bodies. [3] [4] ISRRT is working with the World Health Organization.
The term radiographer can also refer to a therapeutic radiographer, also known as a radiation therapist. Radiographers are allied health professionals who work in both public healthcare and private healthcare and can be physically located in any setting where appropriate diagnostic equipment is located, most frequently in hospitals. The ...
Medical radiation scientists include diagnostic radiographers, nuclear medicine radiographers, magnetic resonance radiographers, medical/cardiac sonographers, and radiation therapists. Most medical radiation scientists work in imaging clinics and hospitals' imaging departments with the exception of Radiation Therapists, who work in specialised ...
In X-ray radiography and radiotherapy, it is radiographers who will carry out the imaging or treatment, while technologists may be involved in equipment testing and radiation protection activities. [ 1 ] [ 10 ] In nuclear medicine however, those with technologist or radiographer training largely have the same responsibilities.
The CDRH cybersecurity vision is to protect patient safety by strengthening medical device resiliency to cybersecurity threats. CDRH provides manufacturers with recommendations to integrate cybersecurity throughout the medical device design process and simultaneously issues safety communications to the public about cybersecurity vulnerabilities ...
Depending on the virus, a variety of genetic changes can occur in the host cell. In the case of a lytic cycle virus, the cell will only survive long enough to the replication machinery to be used to create additional viral units. In other cases, the viral DNA will persist within the host cell and replicate as the cell replicates.
Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...
Cell entry by enveloped viruses is more complicated. Enveloped viruses enter the cell by attaching to an attachment factor located on the surface of the host cell. They then enter by endocytosis or a direct membrane fusion event. The fusion event is when the virus membrane and the host cell membrane fuse together allowing a virus to enter.
